Abstract
Cette invention se rapporte à un système de rotor cycloïdal doté de pales à profil aérodynamique se déplaçant le long d'une orbite généralement non circulaire, allongée et, dans la plupart des modes de réalisation, à variation dynamique. Ladite orbite non circulaire fournit une période plus longue dans chaque révolution et un vent relatif optimisé le long de la trajectoire pour chaque pale, afin de maximiser de façon efficace la sustentation lorsque les orbites sont allongées horizontalement, ou la poussée/propulsion lorsque les orbites sont allongées verticalement. La plupart des modes de réalisation, en plus de comprendre les actionneurs commandés par système informatique pour faire varier de façon dynamique la trajectoire des pales et l'angle d'attaque, peuvent comprendre les actionneurs commandés par système informatique pour faire varier de façon dynamique l'orientation spatiale des pales, en permettant leur déplacement oblique vers le haut/vers le bas et/ou le positionnement de leur flèche vers l'arrière/de leur flèche vers l'avant pour produire et contrôler avec précision divers effets aérodynamiques permettant la fourniture d'une performance optimum pour divers régimes de fonctionnement, neutraliser des rafales de vent et permettre à l'aéronef de se déplacer latéralement. Ainsi le rotor décrit, qui lorsqu'il est utilisé dans un giravion VTOL, nécessitera une puissance de moteur inférieure pour atteindre ou dépasser la performance de fonctionnement des giravions VTOL équipés de rotors de technique antérieure, offre également une efficacité accrue et nécessite moins de puissance lorsqu'il est utilisé pour générer la force de propulsion de divers véhicules ou lorsqu'il est utilisé comme ventilateur.
